This is an example of active transport. This type of diffusion utilizes ATP whereas Passive diffusion don't. There are special pores or transporter proteins in the cell wall of any microbial cell, which allows diffusion of a molecule across it with the consumption of ATP.
Example Sodium Potassium Pump, which allows transport of Na and K across the cell membrane. Here, Sodium is flushed out of the cell and K is taken in via the membrane transporter protein with the consumption of ATP.

Facilitated Diffusion is a form of passive transport as opposed to active transport.
It allows the passage of substances to cross membranes with the assistance of transporter proteins. Some substances such as glucose, sodium and chloride ions cannot pass through the lipid bi-layer of cell membranes. by using ion channel proteins and carrier proteins which are embedded in the cell membrane these type of substances can be transported. The ion channel proteins allow specific ions to pass though a protein channel. They are regulated by the cell and are either open or shut so controlling the passage of the substance into the cell. Carrier proteins bind specific molecules, change shape and then deposit it across the membrane. Once completed they return to their original position.
An example of facilitated diffusion is the movement of a DNA binding protein along a DNA strand. Hope this helps and that it was on time!
its passive transport :)
They are the channels by which molecules enter in facilitated diffusion.
it enters most rapidly by facilitated diffusion!!
Facilitated Diffusion
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Passive transport is when molecules pass freely through the membrane moving from the higher concentration area to the region of lower concentration. Three examples of this are diffusion, osmosis, and active transport.

They are the channels by which molecules enter in facilitated diffusion.
Facilitated diffusion moves molecules through cell membranes passively.
facilitated diffusion
Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.

Facilitated Diffusion
There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
